<h2>Introduction</h2>
<p>
Thank you for downloading the HyperGraphDB distribution, release 1.3. 
HyperGraphDB is an innovative database management system geared towards 
the complexities and open-endedness of modern, data intensive
information systems, in particular the semantic web, artificial intelligence,
networks research and object-orientation. It combines concepts and features of 
several of the major data management paradigms, including graph-oriented and its
cousin object-oriented DBMS as well as the relational model.
</p>
<p>
HyperGraphDB is an embedded database, based on the Java platform and the 
robust and high-performance BerkeleyDB storage system. The storage sub-system is 
pluggable and alternatives to BerkeleyDB are available.

<h2>System Requirements and Installation</h2>
<ul>
<li>Java 6 or later is required to compile and/or run HyperGraphDB.</li>
<li>BerkeleyDB Java Edition is used by default from now on. However, if you want to use
the native version of BerkeleyDB, as older releases of HyperGraphDB have,
you would need a fairly recent version of Linux 32bit/AMD64, Windows 32bit/AMD64 
or Macos.</li>
